Publish these books in your country.
ZAK's Computer Science series covers every Cambridge Computer Science paper — O Level and IGCSE (the current syllabus and the new one examined from 2029) and AS & A Level 9618. We are looking for publishers, distributors, school groups, EdTech platforms and accessibility organisations to bring them to students in print, as ebooks and in accessible editions — in your country, your language and your market.
Why these books
Easy to publish. Hard to beat.
Original questions
Every practice question and mark scheme is written for the books. Past papers are only referenced by paper and question number — there is nothing of Cambridge's to clear for your territory.
Written to the marks
Each chapter is one syllabus section; page space follows Exam Heat — how often a section is set and the marks it earns on the real papers.
Verified answers
Every worked answer — traces, conversions, SQL, logic, assembly — is checked by the companion site's own engines before it is printed.
A free website behind every page
A QR code and short code beside each section open the matching quiz, flashcards, past-paper questions and labs on cswithzak.com — free for every reader, in every country.
A whole series
One book per paper for O Level / IGCSE (current and next syllabus) and AS & A Level 9618, each with a write-in workbook and a Teacher Edition.
Accessible from the source
Dyslexia-friendly, large-print, PDF/UA and EPUB 3 editions come from the same sources, and every diagram is colour-blind safe.
The titles
Every book, every workbook.
Each title below is available for licence on its own or as a series. Open any one to read its free chapter.

Ready for accessibility law
Ebooks sold in the EU must meet the European Accessibility Act. Our EPUB 3 carries schema.org accessibility metadata and the PDFs are tagged to PDF/UA-1, so your digital editions start compliant. Dyslexia-friendly and large-print editions follow published guidance (the British Dyslexia Association Style Guide), and diagrams use the Okabe–Ito colour-blind-safe palette with a pattern and a glyph for every colour.

FAQ
Questions publishers ask.
Are the books endorsed by Cambridge?
No. They are written for the Cambridge International syllabuses (O Level 2210, IGCSE 0478 and AS & A Level 9618) and have not been through the Cambridge International endorsement process. A licensee may apply for endorsement for its own edition; we will help with the files.
Do the books contain past-paper questions?
No. Every question is original. Where a real past-paper question is useful, the book gives its paper and question number so a teacher can find it — nothing of Cambridge's is reproduced, so there is no third-party permission to clear.
Which territories are available?
Any, by agreement — country by country or by region, exclusive or not. Tell us what you have in mind.
Can we translate or adapt the books?
Yes, by agreement. The books are typeset from plain sources, so a translated or adapted edition keeps the layout, diagrams and accessible editions.
What files do we receive?
Print-ready PDF/X-4 with bleed, tagged PDF/UA, EPUB 3 with accessibility metadata, the dyslexia-friendly and large-print PDFs, and the workbooks — for your own ISBNs, cover and imprint.
What about the ebook on cswithzak.com?
The website ebook stays, and the free practice on cswithzak.com stays free for every reader of every edition, including yours.
We are an accessibility organisation.
Under the Marrakesh Treaty, authorised entities can make accessible copies for print-disabled readers. We would rather give you the accessible files directly — choose that organisation type in the form.
